Abstract
The invention relates to apparatuses, a method, computer program and computer-readable medium.
Claims33
An apparatus comprising:
- at least one processor and at least one memory including a computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to:
- define at least one virtual cell covering a geographical area comprising primary users and secondary users, the at least one virtual cell being intended for a second type of communication comprising device-to-device communications;
- determine at least one estimate on potential interference caused by the at least one virtual cell to at least one neighbouring cell of a communication entity using the spectrum as a user of a first type of communication;
- identify available radio resources for usage of the at least one virtual cell, wherein the identification of available radio resources is carried out according to at least one threshold value setting an upper limit for interference towards the at least one neighbouring cell, wherein when the at least one threshold value is met or exceeded, the second type of communication in the virtual cell is not allowed, and when the at least one threshold value is not met, the second type of communication in the virtual cell is allowed;
- and
- select at least one radio resource from the identified available radio resources for the usage of the at least one virtual cell for the second type of communication based on the determined estimates.

- and
- selecting at least one radio resource from the identified available radio resources for the usage of the at least one virtual cell for the second type of communication based on the determined estimates.

A non-transitory computer-readable storage medium, stored thereon a computer program comprising program code which, when executed by a processor, causes the processor to perform:
- defining at least one virtual cell covering a geographical area comprising primary users and secondary users, the at least one virtual cell being intended for a second type of communication;
- determining at least one estimate on potential interference caused by the at least one virtual cell to at least one neighbouring cell of a communication entity using the spectrum as a user of a first type of communication comprising device-to-device communications;
- identifying available radio resources for usage of the at least one virtual cell, wherein the identification of available radio resources is carried out according to at least one threshold value setting an upper limit for interference towards the at least one neighbouring cell, wherein when the at least one threshold value is met or exceeded, the second type of communication in the virtual cell is not allowed, and when the at least one threshold value is not met, the second type of communication in the virtual cell is allowed;
- and
- selecting at least one radio resource from the identified available radio resources for the usage of the at least one virtual cell for the second type of communication based on the determined estimates.
